AD NUMBER: 2012-02-17

SUMMARY: This AD was prompted reports that
several operators have found cracking in the front spar lower chord
at the fastener locations common to the side link support fitting
at wing station (WS) 292. This AD requires repetitive inspections
for corrosion and cracking in this area, and corrective actions if
necessary. The FAA is issuing this AD to detect and correct such
corrosion and cracking, which, if not corrected, could grow and
result in structural failure of the spar.
